Claims

[Scope of utility model registration request]

In a support structure for a radial turbine nozzle attached to a nozzle mounting member, the support structure includes a nozzle vane and a flange to which the nozzle vane is attached to form four high-temperature gas passages to the turbine rotor between the nozzle vane and a turbine shroud, and the flange is attached to the flange. A locking groove is formed, and a pin having one end locked in the locking groove is urged toward the nozzle mounting member by an elastic member interposed between the other end of the pin and the nozzle mounting member. °C
1. A support structure for a radial turbine nozzle, characterized in that the flange is attached to the nozzle attachment member.
